About Turning Point Therapeutics, Inc.

Turning Point Therapeutics is a clinical-stage precision oncology
company with a pipeline of internally discovered investigational drugs
designed to address key limitations of existing cancer therapies. The
company’s lead program, repotrectinib, is a next-generation kinase
inhibitor targeting genetic drivers of non-small cell lung cancer and
advanced solid tumors. Repotrectinib has shown antitumor activity and
durable responses among kinase inhibitor treatment-naïve and pre-treated
patients, and is planned to enter a registrational Phase 2 study in the
second half of 2019. Turning Point’s kinase inhibitors are designed to
bind to their targets with greater precision and affinity than existing
therapies, with a novel, compact structure that has demonstrated an
ability to potentially overcome treatment resistance common with other
kinase inhibitors. The company is driven to develop therapies that mark
a turning point for patients in their cancer treatment.
